Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -20 | -11 | -12 | -19 | -29 | -91.0 | -18.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 2.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -39.2
For the lines, you have the data necessary to plot the chart.
